Unfortunately, it’s that time of year again—the dreaded cold and flu season.
Are you drinking orange juice each morning to avoid catching the cold, or worse yet—flu—that is making its way around your office? Did you know that you may actually be causing more harm than good? While oranges are loaded with nutrition, orange juice contains a high amount of fructose which signals your immune system to take a nap.
The American Journal of Clinical Nutrition has found that fructose is the most powerful suppressor of your leukocyte index (the measurement of how well your white blood cells fight off invaders). In fact, fructose reduces your immune system’s ability to eat invaders by more than 40 percent and takes more than five hours for your immune system to return to normal.
If drinking orange juice isn’t the answer to staying healthy, would you believe that good posture is? As crazy as it sounds, posture actually impacts your immunity. When you tilt your head forward (one of the most common poor posture positions), it causes tension in the spinal cord, which interferes with the messages sent from the spine through the side branches of the sympathetic nervous system. The sympathetic nervous system is the part of our autonomic nervous system that controls heart rate, breathing, digestion, hormone release and defense cells for immunity*.
So this cold and flu season—instead of guzzling orange juice—try some chicken noodle soup, a good night’s sleep and sitting up straight!
